VMware has recently released VMware vSphere APIs for I/O Filtering (VAIO), a handy document that highlights the VAIO I/O Filtering technology operational principles. Here, we shed light on them briefly and discuss how VAIO can be implemented in a production environment.

VAIO is a technology and an API providing the direct access to the virtual machines’ guest OS I/O Stream. VAIO is already employed in partner products for maintaining various tasks (i.e., caching write-back and write-through). VAIO is based on the Storage Policy Based Management framework, dedicated to managing virtual machines storages and set the storage rules.
